guy down the street building a 302 chev and has roller rockers and factory replacement solid cam.
he had it going and took it for a spin and came back popping two cam locks had backed off and rockers right off. couple other loose
took a look at the valve clearance when he had it apart and said way too much .cam stated 24 intake 26 exhaust.
he got the intake off and i asked when did he adjust them. he told me when the piston would be at top dead center. i advised tooo loose as valves will be opening well before that. lifers have to be on bottom of bore when adjusting clearance.
i still think the clearance still seems excessive even at the above specs as the rockers seem really loose at the bottom of the lifter travel.
i have not dealt much with solid cams in cars but clearances shure seem to be a lot even a 24 thou and does this not cause a clatter even when hot?
someone smarter than me please explain excessive clearances on solid cams and why and does this not lead to upper valvetrain and pushrod damage ???
